WitrynaThere are four types of Non-Newtonian fluids, and they are: Dilatant: The viscosity of these fluids increases when shear stress is applied. Quicksand, cornflour with water, and putty are examples of dilatant fluids. Pseudoplastic: The viscosity of these fluids decreases when shear stress is applied. These fluids are the opposite of dilatant fluids.
